replaced crankshaft sensor, mass air flow sensor and cam sensor and car is still stalling out. Dont know what else to do. Had the ICM checked out and it read good. Any thoughts or ideas?

When car warms up it stalls and turns off, especially when making turns. Car starts back up but gauges go crazy.

Engine stalls anywhere-freeway at speed or city trafic. After 25-30 minutes it will restart and run for
various amounts of time-15 minutes to 45 minutes.
car runs then stalls and won't start for thirty minutes.

Stalls when idling, when coming to a stop, and when i go around turns. I have fixed this problem before with gas treatment (Seafoam to be exact) but the problem is back and the treatment hasn't worked the second time.

My vehicle is a 2005 Buick LaCrosse CXS. When fuel up the vehicle it acts like it is flooded and will not start. Once it sets for about 20 minutes it starts and then the engine revs between 2 and 3 RPMS up and down. After you drive it the first time after filling the tank it would act normal again until the next fill up with gas. The dealership said it was a crankshaft sensor, after market gas cap and vent cylanoid back by the gas tank.
